Up front, the 5.25? and 3.5? drive bays are protected by a very solid door. The bottom-front houses a 120mm intake fan, which will help cool your drives while bringing in fresh air to the system. The side panel includes a small window, offering just a sneak peek as to what’s inside. There is an optional 120mm fan spot as well on the side, if you decide you need more direct fresh-air cooling for your video cards, chipset, or CPU.
